Electronic and electromechanical industrial hooters for machine-level warnings, process fault alarms, shift boundaries, and general area alerts. Single tone and multi-tone. 80–110 dB. IP55.
The general-purpose industrial hooter is the most commonly installed warning device in Indian factories — and also the product with the widest range of variants and the most potential for mis-specification. This page covers the full category: what types exist, what applications each suits, and how to select the right one for your requirement.
| Type | How It Works | Best For |
|---|---|---|
| Electronic Hooter / Buzzer | Electronic tone generator with piezo or dynamic speaker | Control panels, machine alarms, PLC outputs, indoor zones |
| Electronic Siren | PCB circuit relayed through horn speaker | Outdoor area alerts, higher ambient noise, noisy shopfloors |
| Multi-tone Hooter | Electronic, multiple tone codes selectable by contact input | Situations needing distinct alarm classes — fault vs trip vs warning |
| Motor Siren | Small motor-driven rotating impeller | Large outdoor areas, high ambient noise, long-range coverage |
| Voice Hooter (MT-PSH) | Pre-recorded voice messages via PA speaker | Crane bays, conveyor pre-start, shift announcement |
| Parameter | Specification |
|---|---|
| Output | 80–110 dB at 1m depending on model |
| Supply voltage | 24V DC, 12V DC, 110V AC, 230V AC — specify at order |
| Tones | 1 to 128 depending on model; single-tone and multi-tone variants |
| Trigger | Potential-free dry contact or direct voltage input |
| Mounting | Wall, panel surface, DIN rail — specify at order |
| Enclosure | ABS plastic (indoor) or die-cast aluminium IP55 (outdoor) |
| Colour | Safety yellow standard; red, grey on request |
| Operating temperature | −10°C to +55°C |
| Cable entry | M20 threaded entry, knockout or conduit |

If your ambient noise is above 85 dB, a standard 90 dB electronic hooter will not be reliably audible. Move up to a multi-tone or motor hooter at 100–110 dB, or use a voice hooter (MT-PSH) directed at the work area from 2–3m mounting height. We'll confirm the right model if you share your ambient noise reading.
